The project will involve the study of stains on fabrics and the factors influencing their removal. Some commons household materials, for example tea, can cause stains on fabric that are very persistent and hard to remove using existing wash formulations. An additional complication in this work is that although these stains can be readily removed when fresh, under certain conditions they age to form persistent and intractable deposits that are much more challenging. This project will study the interactions of molecules present in these stains with the fabric substrate, and look at the effects of other species, for example metal ions, upon their behaviour and persistence. The study will include the use of non-contact spectroscopic methods for the analysis of the materials and extend this to the study of fabrics under wash conditions.

该项目将涉及研究织物上的污渍及其去除的影响因素。一些常见的家用材料，例如茶，可能会在织物上产生非常持久的污渍，并且难以使用现有的洗涤制剂去除。这项工作中的另一个复杂因素是，尽管这些污渍在新鲜时可以很容易地去除，但在某些条件下，它们会老化形成持久和难处理的沉积物，这更具挑战性。该项目将研究这些污渍中存在的分子与织物基材的相互作用，并研究其他物种（例如金属离子）对其行为和持久性的影响。该研究将包括使用非接触式光谱方法分析材料，并将其扩展到洗涤条件下的织物研究。
